L
ike 40 cars on a fog-shrouded
California highway, there’s a pile-up
happening in most commo shops.
That pile is made up of SINCGARS
LS-671 loudspeakers.
Why are they piling up?
The flexible ribbon cable inside
the LS-671 is torn and the loudspeak-
er is silent.
Why is the ribbon cable torn?
Because operators are trying to
connect the CX-13292 cable that runs
from the SINCGARS mounting base
to the speaker by twisting it on.
Unfortunately for the loudspeaker,
this connection is not a twist-on. To
attach this connector, you push it on
and then tighten it down with the
locking mechanism on top of it.
When you try to twist it on, you
may dislodge the other half of the
connector from the loudspeaker. If it
moves, it will tear the ribbon cable.
Operators, stop this pile-up in the
commo shop. Give up the twist!
Learn to push and lock!

Dear Editor,
The mast element of the AS-3916/VRC antenna often comes loose
from the base, because the collet, NSN 3460-01-435-8079, is too
long to hold it tight.
The problem is the collet bottoms out
before adequately clamping onto the element.
This can be solved by unscrewing the col-
let from the antenna base and filing off 1/16
of an inch from the collet bottom.
This lets the collet be tightened fully and
stay tight like it should.

Too many new antennas are ordered
because of this problem. This simple solution
will save a great deal of money. Great job, George.
